HP Pavilion 17-ab004 Notebook PC does not turn on

HP Pavilion 17-ab004
Microsoft Windows 10 (64-bit)

The laptop was running on battery power. I closed the lid, the laptop went into hibernation, then I opened the lid, pushed the buttons, the laptop did not exit this mode. I turned it off with the power button, but I couldn’t turn it on anymore. When you press the power button, the laptop does not turn on. There is no image on the screen, the cooler does not spin, only the power button is on. I took the laptop to the service, the master said that as a result of a burnt capacitor, the multicontroller died. There is a short circuit, and after removing the multicontroller, all voltages appeared. In the service, the master changed the capacitor and multicontroller, but this did not help. It got worse. The power button is now off. I decided to buy a new motherboard. I changed it myself. Pre-photographed everything, just as well connected everything. Turn on, and the exact same picture. The laptop does not start, the power button is on, the cooler is not spinning. Peripherals are not connected, one memory bar was installed in the board. Included from the power supply. Dear masters, I ask for advice, what could be the reason?
